I don't buy a lot of DVD's but got this one. IMO, this is one of the best DVD's I've seen in terms of picture & sound quality. I found an interesting review at amazon.com:
"In a word, spectacular. Thanks to a new digital transfer, you've never seen C-3PO glow so golden, and Darth Vader's helmet is as black as the Dark Side. And at the climactic scene of A New Hope, see if the Dolby 5.1 EX sound doesn't knock you back in your chair. Other audio options are Dolby 2.0 Surround in English, Spanish, and French. (Sorry, DTS fans, but previous Star Wars DVDs didn't have DTS either.) There have been a few quibbles with the audio on A New Hope, however. A few seconds of Peter Cushing's dialogue ("Then name the system!") are distorted, and the music (but not the sound effects) is reversed in the rear channels. For example, in the final scene, the brass is in the front right channel but the back left channel (from the viewer's perspective), and the strings are in the left front and back right. The result feels like the instruments are crossing through the viewer."
